Secondary succession
Explanation:
The type of succession in this forest is a secondary succession.
A secondary succession is from of succession that occurs in a place that lost it already established ecosystem.
It is succession in an area with soil already formed.
Primary succession is succession in a completely destroyed area that has lost its ecosystem components.

- Then shrubs and more vegetation grows.
- With time, perennial forest trees surfaces and the forest is restored.
- Secondary succession is faster

Answer:
They became different.
Explanation:
Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.
2 + 9x = 20
2 - 2 + 9x = 20 - 2
9x = 18
9x/9 = 18/9
x = 2
